"I can’t tell you how much modeling changed my life – I am just so much more confident in myself," she told H&M magazine.

"I sort of take pride in not doing botox or any of that face stuff. That look just seems so forced and strange to me. I am happy with the way I am. And I am here, you know? Doing a swimwear shoot today!"

Writing on her Instagram, McLeod said she believes "60 is the new 20".

Revealing that she had the best time of her life during her 50s, she wrote: "This past decade disappeared in a nanosecond. There were some very fierce obstacles in my way but I hung in there and now here it is. 60."
